I have 50A Victron Phoenix charger to charge 4 Exide Sealed Lead Acid batteries. When the batteries need changing I plan to get Trojan Gels. Charger and Batteries are located in the engine room and so I would say close to outside temperature when moored.
Reading the Trojan literature they state that Temperature Compensation should be 0.028V per cell for every 10 degrees below or above 25 degrees. So, if I am correct, at 10 degrees you would need to add 0.028*6= 0.168V. The Absorption Voltage is 14.4 so it should then be at 14.568.
I have my charger set at an Absorption Voltage of 14.4 but when charging today, around 10 degrees, the Voltage is up to 14.8. I cannot find anywhere to set the Victron Compensation so it looks like it is adding >0.04 Vpc per 10 degrees.
When I change to the Gels is this going to be an issue that it is charging at a higher than recommended voltage or am I worrying too much? If it is, is there anyway to alter the setting on the Victron?
